On each day, 0.6 hectare of corn and 1.0 hectare of grass are to be irrigated .Readily available water for corn is 8cm and readily available water for grass is 15 cm . Corn field has 26 furrows each discharges 19 lit/min and grass field has 70 furrows and each discharges 27 lit/min Assume that water is uniformly applied over filled . Find the application efficiency for
a. Corn field
b. grass field
c. Entire field

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
